The only thing about Goroh is that you'd have to make his moveset from scratch. What would be the design behind Goroh? Not being condescending, I kinda wanna make this fun.Samurai Goroh is the better rival to Captain Falcon IMO, he's been there since the beginning too. If we want to add an F-Zero baddie he's the better option if you ask me... Black Shadow is fine, but that movement really is 99% driven by wanting to stick Ganon's moveset on someone else. It's a shame since F-Zero characters are actually very cool.
I'm thinking something like a SamSho character. Make him pretty commital, but powerful and with fast grabs/jabs and throws.
